MEANS FOR THREADING SHUTTLES.

Specification of Letters Patent.

Patented July 14, 1914:.

Application filed August 26, 1913. Serial No. 786,708.

To all whom it may concern.-

Be it known that L GEORGE l3. HAYES, a citizen of the United States, residing at Eagleville, in the county of Tolland and State of Connecticut-, have invented a certain new and useful Improvement in Means for Threading Shuttles, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates chiefly to the class of shuttles now commonly used in weaving cotton, woolen, and silk, fabrics, and my present object is to provide simple, effective and reasonably cheap means whereby such shuttles may be instantlythreaded without having to resort to the almost universal and unsanitary practice of sucking the thread end through a guide-eye in the shuttle body.

Briefly described my said invention consists mainly of a plate fixedly located in the shuttle body adjacent to the delivery end of the bobbin or cop of filling thread; said plate being of such contour, and so located withrespect to the guide eye in the shuttle body, that it (the plate) will serve to guide a bight of the filling thread to the said eye and so that the thread may be readily grasped and drawn therethrough.

My said invention is clearly illustrated in the annexed drawings, Figure 1 being a top or plan View of a shuttle embodying my improvement, and Fig. 2 is a side elevation of the end portion of said shuttle in which my new threading device is located. Fig. 3 is a transverse, sectional, view of said shuttle taken on the line 3-3 of Fig.1. Fig. 4; is a view similar to Fig. 2, with the side wall of the shuttle body broken away to disclose what I term the threading plate and Fig. 5 is a plan view of the shuttle end partly broken away for the same purpose. Figs. 6, 7 and 8 are diagrammatic views illustrating particularly successive steps in the operation of threading a shuttle.

Referring to these drawings the numeral 10 indicates the body portion of a shuttle of the class used in cotton, woolen and silk weaving and 11 indicates a cop of filling thread mounted upon a spindle 12 in the usual manner.

The body 10 is slotted longitudinally, and vertically, as at 13, at the end adjacent to the delivery end of the cop 11 and said slot is connected with a guide-eye 14;, at the side of the shuttle, by a diagonal slit15. Located in the slot 13, and extending downward, diagonally, in slit 15, is a threading plate 16 of thin but stiff material, preferably metal, whose upper edge is approximately flush with the upper face of the shuttle body and whose lower edge is approximately flush with the side wall of said shuttle body, as

is perhaps best understood by reference to Fig. 3 of the drawings. The rear end portion of the threading plate 16 is supported rigidly in the slotted and slitted shuttle body bypins, screws or rivets 17 and 18 and in such manner that the major part of plate 16 is out of contact with the adjacent walls or the slot 13 and slit 15. The upper edge of plate 16 is approximately parallel with the top ofthe shuttle body, the lower edge of said plate is approximately parallel with the side wall of said body, while the free, front, endofsaid plate is more or less undercut, or beveled rearward as at 16*.

In the operation of threading up a shuttle of my described construction the end portion of the filling thread is grasped and a bight of said thread is passed over the front end of plate 16 as seen in Fig. 6 of the drawings. As the thread end is drawn quickly rearward (in the direction of the arrow in said Fig. 6) the bight of the thread slips downward along the under edge 16 and rearward until it is checked by the pin 18 (see Fig. 7 in which position the bight of said thread lies exposed in the guide-eye 1.4: where it may be easily grasped and drawn through said eye (see Fig. 8), when the thread will render around the pins 17 and 18. When the shuttle is traveling forward in the batten the thread is kept from contact with the wooden shuttle body by the pin 18 and when the said shuttle is traveling in the opposite direction the thread is kept from engagement with the shuttle body by a pin 19 fixedly located at the front end of the guide eye 13. In the operation of drawing the bight of the thread through the said eye a hook may be used, as suggested in Fig. 7, or the thread may be started through the guide eye by a wiping movement of the operators thumb against, the side of the instantly and without fail, and without experience, skill or special implements.

Having thus described 1 my invention I claim as new and wish to secure by Letters Patent l. A shuttle of the class vdescribed comprising a bodyportion slotted longitudinally and vertically adjacent the delivery end,

of the cop and having a 'slot connected with the guide eye at the side of the'shuttle by a diagonal slit, a threading plate of thin stiif material located in said slot and extending "downwardly and diagonally with which the thread will render, and one of said pins serving to keep the thread from contact with the shuttle body when the shuttle is travelingin one direction, and a pin fixedly located'at the front end of'the guide eye independent of said plate and serving to keep the thread from engagement with the shuttle body when the shuttle is moving in the other direction.

2. In-a shuttle of the class described, a

a thin flat threading plate located in said slot and extending downwardly in said diagonal slit with its upper edge approximately flush with the upper face of the shuttle body and its lower edge substantially flush with the side wall of said body, means supporting the rear portion of said plate rigidly, with the major portion out of contact with the adja cent walls of said slot and slit, said'means serving also to keep the thread from contact with the shuttle body when the shuttle is traveling in one direction, the free front end of said plate being beveled rearwardly, and a pin fixedly disposed at the front end of the guide eye for keeping the thread from engagement with the shuttle body when the shuttle is moving in the other direction, said pin being disposed adjacent the lower portion of the said beveled edge of said plate.
